After about 50,000 to 75,000 hours of operation has been completed, the DVD-RW burner could be expected to experience a failure according to optical drive vendors and other analysts. It doesn’t matter whether the PC is actually active or in standby mode it simply is just drawing power. After vigorous use, a drive failure can occur easily just within a few months. For about five years or even more, the best drives could keep on working. The biggest enemy of your drive is none other than heat. Improving the internal air circulation surely helps. Does anyone have anything to comment?
